On the show today, Keeley takes the plunge to find out why the RNLI's latest campaign could save your life if you end up in cold water this summer. Jules is in the Cotswolds discovering how men's sheds are being used to help tackle rural loneliness.

Margherita is in Cornwall getting up close and personal with some unusual furry mammals, with a pioneering project that is reintroducing beavers for the first time in centuries to help tackle flooding.
